After three rounds of severe weather Sunday, the KNIA/KRLS Severe Weather Action Team was back on the air Monday for another warning. The southeastern quarter of Marion County was placed under a Severe Thunderstorm Warning at 3:14 p.m. Monday afternoon. The full Severe Weather Action Team briefly hit the airwaves until the warning was quickly cancelled almost 30 minutes minutes later as the strongest part of the storm moved into Mahaska County. National Weather Service trained storm spotters Dr. Bob Leonard and Karen Overgaard called in reports from south of Knoxville and Melcher-Dallas. Heavy rainfall continued to pound parts of Marion County through the evening hours, prompting a Flash Flood Warning in the southeastern quarter of Marion County until 10:15 p.m.
